Chapter 10 Measurement commands

47090/323

257

Example

:MEASure:EGPRs:ARRay:RFTX:ALL 2

:FETCh:EGPRs:RFTX:ALL?

In this case, the sequence of the most important EGPRS RF TX measurements is performed twice. All 34 measurement

result values are kept in an internal memory until they are read out with the FETCh command. After the internal

memory has been read out, it is cleared.

Note: A subsequent :FETCh command (without any previous start of a measurement) therefore tries to read

non-existing measurement data and thus create a timeout error.

:MEASure:EGPRs:ARRay:RFTX:ERMS

Syntax

:MEASure:EGPRs:ARRay:RFTX:ERMS <int1>

Parameters

int1 is an integer.

The minimum value for int1 is 0, the maximum value is 100. The default value for int1 is 0.

Description

Measures multiple times (set with the int1 parameter) the error vector magnitude rms-averaged over a burst. EVM is

a relative value and shown as a percentage. To read out the entire measurement results array, use the

:FETCh:EGPRs:RFTX:ERMS command.

Query

The query form of this command returns a string, containing int1 floating point real numbers with the physical

dimension of %, representing the measurement results.

The single measurement results are separated by commas.

Example

:MEAS:EGPRs:ARR:RFTX:ERMS 5

:FETC:EGPRs:RFTX:ERMS?

The error vector magnitude rms-averaged measurement is performed five times. The measurement results are stored

internally and read by the FETC command. An example of the string returned is: "2.33,2.53,1.97,2.41,1.79".
